Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662028, here are decompositions:

7 + 8662021 = 8662028
19 + 8662009 = 8662028
31 + 8661997 = 8662028
127 + 8661901 = 8662028
139 + 8661889 = 8662028
157 + 8661871 = 8662028
229 + 8661799 = 8662028
457 + 8661571 = 8662028

Showing the first eight; more decompositions exist.
